Materials Needed
Before you cast on, gather the following supplies. All materials are readily available at your local yarn shop or online retailer.
Yarn
- Worsted weight yarn (Category 4) in three colors:
- Main Color (MC): Soft Cream – approximately 1000 yards (915 meters)
- Contrast A: Sky Blue – approximately 200 yards (183 meters)
- Contrast B: Sunshine Yellow – approximately 150 yards (137 meters)
- Tip: Choose a machine-washable yarn like acrylic, cotton, or a superwash wool blend for easy care—essential for baby items!
Needles & Notions
- US Size 8 (5.0 mm) knitting needles (or size needed to obtain gauge)
- Tapestry needle for weaving in ends
- Stitch markers (at least 2)
Gauge
18 stitches and 24 rows = 4 inches (10 cm) in Stockinette stitch (knit one row, purl one row). Always knit a gauge swatch before starting to ensure your finished blanket matches the intended dimensions (approximately 36 inches wide x 40 inches long). Adjust needle size if necessary.
Step-by-Step Instructions
This afghan is worked flat in one piece, making it a portable and straightforward project. Follow the pattern carefully, and you'll have a beautiful, milestone-ready blanket in no time.
Pattern Notes
- The afghan is worked from the bottom up, with a garter stitch border framing the central track panel.
- The central panel features a repeating "track" stitch pattern—a combination of knits and purls that creates a subtle raised rib.
- Mile-marker stripes are created with short rows of contrasting color. Carry the main color yarn up the side when not in use to avoid cutting and re-joining.
- All slipped stitches are slipped purlwise with yarn in back (wyib) unless otherwise noted.
Abbreviations
- K: Knit
- P: Purl
- Sl: Slip
- YO: Yarn over
- K2tog: Knit two together
- PM: Place marker
- SM: Slip marker
- RS: Right side
- WS: Wrong side
Cast On
With Main Color (MC), cast on 100 stitches loosely. A long-tail cast on works beautifully here—just be sure not to pull too tightly, as the edge should remain stretchy.
Border (Garter Stitch)
Rows 1-10: Knit all stitches. This creates a classic garter stitch border (all knit stitches on both sides) that will frame the blanket beautifully.
Main Body – First Section
Row 11 (RS): K10 (border), PM, K80 (center panel), PM, K10 (border).
Row 12 (WS): K10, P80, K10.
Repeat Rows 11-12 for 10 more rows (total 22 rows from cast on). This establishes the stockinette stitch center with garter stitch borders.
Begin Track Pattern (Center Panel Only)
Row 23 (RS): K10, PM, *K4, P2* repeat from * to * until 4 stitches remain before marker, K4, SM, K10.
Row 24 (WS): K10, *P4, K2* repeat from * to * until 4 stitches remain before marker, P4, K10.
Repeat Rows 23-24 for 20 rows (total 40 rows of track pattern). This creates the raised ribbed "track" effect that runs vertically through the center.
Mile Marker Stripe – Contrast A (Sky Blue)
Row 43 (RS): K10, with Contrast A, K80, K10 (do not cut MC, carry it up the side).
Row 44 (WS): K10, with Contrast A, P80, K10.
Row 45 (RS): K10, with Contrast A, K80, K10.
Row 46 (WS): K10, with Contrast A, P80, K10.
Cut Contrast A, leaving a 6-inch tail for weaving in later.
Continue with Main Color
Rows 47-48: Repeat Rows 11-12 (K10, K80, K10 on RS; K10, P80, K10 on WS).
Repeat Track Pattern
Work Rows 23-24 for 20 more rows (total 40 rows of track pattern). This second track section mirrors the first, maintaining the rhythmic texture.
Mile Marker Stripe – Contrast B (Sunshine Yellow)
Repeat Rows 43-46 using Contrast B (Sunshine Yellow). Remember to carry MC up the side and cut Contrast B after completing the stripe.
Continue with Main Color
Rows 47-48: Repeat Rows 11-12.
Repeat Track Pattern
Work Rows 23-24 for 20 more rows (total 40 rows of track pattern).
Mile Marker Stripe – Contrast A (Sky Blue)
Repeat Rows 43-46 using Contrast A (Sky Blue) again. This creates the alternating blue-yellow-blue stripe sequence.
Continue with Main Color
Rows 47-48: Repeat Rows 11-12.
Repeat Track Pattern
Work Rows 23-24 for 20 more rows (total 40 rows of track pattern). This final track section completes the central design.
Final Border
Rows 1-10: Knit all stitches. This mirrors the bottom border, creating a symmetrical frame.
Bind Off
Bind off all stitches loosely in knit. Use a larger needle or a stretchy bind-off method (like the Jenny's Surprisingly Stretchy Bind-Off) to ensure the edge remains flexible and doesn't pucker.
Finishing Touches
- Weave in all ends using a tapestry needle. Be sure to weave in the carried MC yarn along the side seam carefully, and secure all color-change tails.
- Block gently to the specified measurements (approximately 36 inches wide x 40 inches long). Wet blocking or steam blocking works well—just follow the yarn label's care instructions.
- Once dry, your Marathon Mile Marker Baby Afghan is ready to gift or keep!
Tips for Success
- Count your stitches after each row, especially when working the track pattern, to catch mistakes early.
- Use stitch markers to clearly delineate the border from the center panel—this prevents accidental increases or decreases.
- Carry the MC yarn loosely up the side during stripe sections to avoid puckering. Twist it with the contrast yarn at the edge if needed.
- Blocking is essential to even out the stitches and achieve the final dimensions. Don't skip this step!
This pattern is a labor of love, but the result is a stunning, meaningful keepsake that will be treasured for years. Whether you're knitting for your own little one or as a gift, the Marathon Mile Marker Baby Afghan is sure to become a family heirloom. Happy knitting, and may every mile marker bring joy!
